Lumbar-sacral vertebra pedicle screw TI-5.5 / 6.0

thoraco-lumbarsacro-iliac jointcannulated

The system consists of pedicle screws, titanium rods, set screws, and other components. The pedicle screws feature a central cannulated design that supports minimally invasive percutaneous pedicle screw fixation. This design helps reduce blood loss, muscle and soft tissue disruption, postoperative pain, incision size, and recovery time, while maintaining reliable reduction and fixation. The minimally invasive approach also supports earlier mobilization and rehabilitation. Spinal minimally invasive surgery is characterized by precise operation, reduced tissue trauma, rapid recovery, and smaller incisions. Primary Function The system is designed to help restore vertebral alignment and physiological spinal curvature while providing partial or complete mechanical support for conditions such as vertebral fractures, lumbar disc herniation, spinal stenosis, and spondylolisthesis. Through a posterior approach, pedicle screws are inserted into the thoracolumbar vertebrae through the pedicles. Distraction, compression, lifting, and reduction maneuvers can then be performed to restore spinal alignment. The rod is introduced subcutaneously into the U-shaped slots of the pedicle screws using dedicated instruments and secured with set screws. The resulting construct provides stable fixation and a biomechanical environment for thoracolumbar fusion. All components are made of TC4 titanium alloy. -Features Pedicle Screw The pedicle is a strong bony structure connecting the vertebral body and lamina and provides a reliable foundation for pedicle screw fixation.
